Hello, In Siemens if you go in technical specifications of any CPU, you will found terms of: CPU Processing times
According to your application and also some experience, you can decide how much speed you will need for your project. And select the optimum CPU to do the job in time. Here's One of S7-300 CPUs data sheet as an example, see the term of CPU processing times. Also see the following link for compare S7-300 CPUs. S7-300 CPUsIf you could get the same term "Bit and word operation times" for instance from other CPUs produced by other vendors, your comparison will be easy. |

Thanks for your PDF files, but I can't find any detailed specifications for the CPU mit 208 Pins at internet. Could you help me for that? Regards, Mo. Rahmandoost |

Hello Everyone, 4 years ago I was asked by one of my customers about processor speed in MHz of S7-400H CPUs and whether it's a multi-processor based or not . I told him about instruction processing times but his mind was locked to processor speed in MHz to compare it with other controllers from other vendors. Strangely, in the very next year Siemens released the 410 CPU for PCS7 with the following specifications:
I know it's useless but Siemens gives this piece of info. only for 410 CPU to avoid this silly question in DCS market. @ Rahmandoost, I think you should contact Siemens. Maybe they can give you an answer. Best regards, H-H |
